Perhaps one step farther might be loosely affixing the reflective
barrier to the rear of the painting, allowing the wall the ability
to breathe a lot, which it would need, and allowing the rear of the
painting to breath just a little, which is what it probably needs.
In addition, the barrier would be invisible from the usual  viewers'
positions in the rooms, could be done before hanging, and would
travel with the painting,during the process of hanging the work.
